__**Samples**__

 * June 14, 2012: There was heavy rainfall the day prior to this sample being collected. While there was found to be a very high number of coliform bacteria, no E.Coli were found on the plates.

 * June 21, 2012: There was no rainfall the day prior to this sample being collected. There was a moderate amount of coliform found and an average count of 233.33 for E.Coli (cfu/100mL).

 * June 28, 2012: There was no rainfall the day prior to this sample being collected. There was a moderate-to-low amount of coliform found and an average count of 100 for E.Coli (cfu/100mL).

Even though no E.Coli was found on the first samples plates, the much higher level of coliform found suggests that bacterial counts significantly spike after a rainfall event. This is likely due to polluted runoff coming from the surrounding urban environment.
